Answer in Brief
Long answer question.
What is hydroponics? How is it useful in identifying the role of nutrients?
- Hydroponics is a technique in which plants are grown in nutrient solutions in absence of soil. Roots are immersed in an adequately aerated, dilute, and defined solution of nutrients. Purified water and mineral salts are used in the nutrient medium.
- In hydroponics, the concentration of a particular mineral in a solution of nutrients in which roots are immersed can be increased or decreased. By this method, essential elements can be identified and their deficiency symptoms can be discovered.
Thus it helps to identify the role of nutrients in plant growth.
